Inventor: KNAPP HERBERT
IPC: H03K23/66
Filed: 1998-09-07
Abstract: A frequency scaler with an input side f/2 frequency divider (H) which forms an intermediate signal (1) from an input signal (IN) with frequency f, the intermediate signal having only the frequency f/2. A device for synchronised inversion (DINV) which, independently of a control signal (MOD), in the case of a required frequency scaling factor of 1/N, switches the intermediate signal (1) directly through to an input of a scaler-expander (EXT) and in the case of a required frequency scaling factor 1/(N+1), the intermediate signal is inverted after N-periods and synchronised with the intermediate signal and switched through to the input of the scaler-expander, in which the output of the scaler-expander supplies an output signal (OUT) with frequency f/N or f/(N+1).

Title: Circuit breaker with automatic catch to prevent rebound of blow open contact arm
Inventor: EBERTS WILLIAM GEORGE
IPC: H01H1/22
Filed: 1998-11-06
Abstract: The outside poles (7a, 7b) of a three pole circuit breaker (1) are each
provided with a blow open latch (87) which includes a latch hook (89) having an open
slot (91) forming jaws (93) pivotally mounted on the contact arm (27). A torsion spring
biases (101) the jaws (93) to a cocked position in which they are aligned for engagement
with a fixed stop member (75) toward which the contact arm (27) rotates as it blows open
in response to the magnetic repulsion forces generated by a short circuit. As the jaws (93)
engage the stop member (75), the latch hook (89) is rotated to mechanically latch the latch
hook (89) on the stop member (75) thereby preventing rebound and reclosing of the
contacts (9). A leaf spring (103) mounted on the crossbar (53) holds the latch hook (89)
in mechanical engagement with the stop member (75). As the circuit breaker (1)
responds to the overcurrent condition and rotates the crossbar (53), the leaf spring (103)
disengages from the latch hook (89) so that the torsion spring can rotate the latch hook
(93) back to the cocked position for disengagement from the stop member (75) upon
reclosing of the circuit breaker (1).

Abstract: Dielectric parts 12 which become resonators are fitted in holes formed in a dielectric
substrate 11 and magnetic parts 13 for setting resonance frequencies of the dielectric parts
12 are also fitted in holes formed in the dielectric substrate 11. With such construction in
which the dielectric parts are fitted in the holes of the dielectric substrate, the physical
preciseness of a high frequency filter is improved. Further, by fitting not only the dielectric
parts 12 but also the magnetic parts 13 in the holes of the dielectric substrate 11, it is
possible to form the high frequency filter operating in a frequency band of several tens
GHz as a micro wave integrated circuit to thereby improve the uniformality and mass-producibility
of the high frequency filter.

Abstract: L'invention concerne la transmission téléphonique d'un son à trois dimensions. Les systèmes de visioconférence souffrent du désavantage lié au fait qu'après la transmission des paroles d'une personne, la voix de cette dernière a tendance à 'se désincarner', ce qui veut dire que si la personne se déplace par rapport au microphone, la voix reproduite a tendance à ne pas se déplacer avec elle. L'invention élimine ou atténue cet effet grâce au système suivant: on obtient des signaux monophoniques gauches et droits, on les modifie de façon à compenser les fonctions de transfert air/oreille de la tête, et on effectue une égalisation et une annulation de la diaphonie sur les signaux. Pour finir, afin de produire un signal binaural comprimé pouvant être transmis par une liaison téléphonique, on comprime les signaux de façon à diviser les fréquences en bandes séparées, mais à conserver les différences de phase entre les signaux transportés dans des bandes de fréquence différentes. Les sons à trois dimensions peuvent ainsi être transmis par des liaisons téléphoniques et reproduits plus efficacement que cela n'était possible jusque-là.
